EVALUATION OF PROTEOLYTIC AND FIBRINOLYTIC ACTIVITY OF BLOOD PLASMA IN COMORBID CHRONIC CORONARY SYNDROME, CHRONIC OBSTRUCTIVE PULMONARY DISEASE, AND OBESE

The aim - to assess the proteolytic and fibrinolytic activity of blood plasma in comorbidchronic coronary syndrome (CCS), chronic obstructive pulmonary disease (COPD), andobese.Material and methods. The study involved 110 patients, who were divided into 5 clinicalgroups: G1 – 22 CCS and obese patients, G2 – 22 COPD and normal body weightpatients, G3 – 22 CCS, COPD and normal body mass index (BMI) subjects, G4 – 22CCS, COPD and overweight patients and G5 – 22 CCS, COPD and obese I, II degreepatients. The control group consisted of 20 healthy individuals. Proteolytic activityof blood plasma was assessed by the lysis of azoalbumin, azocasein, and azocol, andfibrinolytic – by the lysis of azofibrin.Results. There was a significant increase 50,5%, 43,3%, 43,8% (p<0,05) azoalbuminlysis in the fifth participant’s group compared with the 1st, 2nd, and 4th groups. An increasein azocasein lysis 38,08% was observed (p<0,05) in CCS, COPD, and obese patientscompared with CCS, and obese patients. Azocol lysis was significantly higher 41,7%,13,8%, and 22,06% (p<0,05) in CCS, COP, and obese patients compared with the first,second, and fourth groups. Total fibrinolytic activity (TFA) of blood plasma was 17,7%,14,89%, 21,27% (p<0,05) lower in the 3rd, 4th, and 5th patients’ groups compared withthe 1st one. Enzymatic fibrinolytic activity (EFA) of blood plasma was 28,29%, 22,19%,35,85% (p<0,05) lower in the 3rd, 4th, and 5th patients groups compared with the 1st one.EFA level decrease 23,77% (p<0,05) was observed in the fifth group compared with thesecond one.Conclusions. The most pronounced changes in proteolytic (increased azoalbumin,azocasein, and azocol lysis) and fibrinolytic (decreased total and enzymatic) activitiesof the blood plasma in comorbid chronic сoronary syndrome, chronic obstructivepulmonary disease, and obese patients.
